摘要： Firearms, and components of firearms, improve shooting accuracy and tolerance to debris/elements that may enter the receiver during use of the firearm in the field. The outer surface of the barrel and the receiver inner surface, and/or the bolt lugs and the receiver inner surface may feature tight-tolerance or press-fit mating, to enhance axial alignment for shooting accuracy. The bolt lugs may be configured to provide said tight-tolerance mating with the receiver when in the loaded and locked position, but may also be configured to provide space for accommodating debris/elements that enter the firearm so that bolt movement is not hindered by the debris/elements, and operation of the bolt, including cycling of the bolt in the firearm action when the shooter goes to load the next round, is smooth and consistent.

摘要： Components of a firearm having a bolt with locking lugs improve shooting accuracy, due to increased coaxial alignment between the bolt, the cartridge, the receiver, and/or the barrel of a firearm. The receiver inner surface is shaped for lug-cleaning and for close tolerance/mating with the lugs only in the locked position and also with a non-threaded, axial surface of the barrel. Thus, the mating surfaces that are instrumental and/or that mainly control coaxial alignment of the receiver, bolt, and barrel are located between the lug stops and the threaded end of the receiver. The lugs may be axially curved or otherwise axially non-linear to tolerate dirt and other debris in a field environment.

摘要： Firearms, and components of firearms, improve shooting accuracy, due to increased coaxial alignment between the receiver and the barrel of the firearm. The outer surface of the barrel and the receiver inner surface feature extremely-tight-tolerance/press-fit mating of one or more outer axial mating surfaces of the barrel with one or more axial portions of the receiver inner surface. The extremely-tight-tolerance/press-fit axial mating surfaces may be distal of, proximal of, in-between, and/or otherwise outside and separate from the threads or conventional connection means for connecting the barrel to the receiver.
